ToaZZ whom it may concern Be it known that I, IRWIN F. KRPLER, a citizenof the United States, residing at Akron, in the county of Summit andState of Ohio, have invented certain new and useful Improvements inWater Bags or Bottles, of which the following is a specification.

My present invention pertains to an improved water-bag or bottle, thesame being illustrated in the annexed drawings7 wherein:

Figure 1 is a perspective view of the bag, a part of the edge ormarginal portion being broken away to illustrate the construction ofsuch portion; Fig. 2 a longitudinal sectional view of the bag, showingthe molds in which it is finally formed and the thimble or valve-socketwhich is vulcanized in the throat of the bag; Fig. 3 an end elevation,partly in section, of the bag and the molds, the same being on asomewhat enlarged scale; and Fig. l a perspective View of the combinedthimble or socket-carrier and the funnel mold.

The object of vthe present invention is to produce a bag or bottlewithout the use of seam-covering strips, separate throat pieces or thelike which, as well known, are the weak points in such bag structures,frequently being the cause of the development of leaks. Furthermore, thebag which forms the basis of the present invention has a threadedthimble or socket-piece, vulcanized in position during the process ofmanufacture of the bag or bottle, thereby insuring a tight joint betweensuch member and the .throat of the bottle.

The method by which the bag covered by the present application isproduced forms the subject-matter of my cO-pending application filed onor about January 17, 1912, Serial No. 671,673, the present case being adivision thereof.

In Order that the inventionl may be clearly understood, a generalstatement of the process by which the bag or bottle is produced will begiven. The bag` is produced in halfsections, each section being formedin a mold and partially cured. The marginal portion of each section isforced outwardly over the edges of the mold beyond the ultimate edge ofsuch section, the fin or protruding portion thus formed being severed orcut off so as to produce a homogeneous surface or edge. The two halvesthus formed are then placed face to face and the bag is finallyvulcanized. Irior to the complete vulcanization, however, the socket Orthimble is positioned in the mouth of the bag and vulcanized in place atthe same time that the marginal portions are secured to each other bysuch vulcanization. During the process of producing the half sections,the marginal portions are thickened and provided with a projectionwhich, when the parts are nally vulcanized, forms a bead around theouter edge of the bag and, owing to the pressure exerted by the molds, afin is likewise produced upon the inner portion of the bag along theline of contact of the marginal portions of the two sections where theyare brought together prior to the final vulcanization.

Referring to the drawings in which the final molds are alone shown, 1denotes one member of the mold and 2 the opposite member. Thefunnel-mold and socket-carrier 3 are shown in Figs. 2 and l, the samebeing designed to coact with the mold sections 1 and 2 to form thefunnel 4, and the tab or projection 5 thereon, and likewise to carry thesocket or threaded nipple 6, which is vulcanized in place in the throatof the bag while the two sections are being finally united.

In Figs. 2 and 3 the two half-sections of the bag, which are ultimatelysecured together, are denoted by 7, and where they are joined togetherat their edges there is produced a thickened edge or marginal portion 8,having a bead 9 extending along the outer edge thereof entirely aroundthe bag up to the throat 10 thereof. Said bead merges at the lower endof the bag into a tab 11, having an eyelet 12 therein. A fin 13 ispreferably formed upon the inner face of the bag or bottle -opposite thebead 9, said fin, bead and thickened marginal portion rendering the bagstronger at those points where ordinarily such bags are the weakest. Inother words, there is produced a bag which is virtually an integralstructure throughout, without seam or joint, and having the valvesocketfirmly vulcanized in place in the throat 10. rlhe reinforced edgeinsures strength and stability in the structure.

I-Iaving thus described my invention, what I claim is:
